Serial EEPROM Series Standard EEPROM

I2C BUS EEPROM (2-Wire)

BR24Gxxx-3A (128K 256K 1M)

General Description

BR24Gxxx-3A is a serial EEPROM of I2C BUS Interface Method

Features

Packages W(Typ) x D(Typ)x H(Max)

„ All controls available by 2 ports of serial clock(SCL) and

serial data(SDA)

„ Other devices than EEPROM can be connected to the

same port, saving microcontroller port

„ 1.7V to 5.5V Single Power Source Operation most

suitable for battery use

„ 1.7V to 5.5V wide limit of operating voltage, possible

1MHz operation

„ Page Write Mode useful for initial value write at factory

shipment

„ Self-timed Programming Cycle

„ Low Current Consumption

„ Prevention of Write Mistake

¾ Write (Write Protect) Function added

¾ Prevention of Write Mistake at Low Voltage

„ More than 1 million write cycles

„ More than 40 years data retention

„ Noise filter built in SCL / SDA terminal

„ Initial delivery state FFh
